Laws of UX
There are certain UX Laws which can help you to create a better user experience.
Fitts’s Law
The time to acquire a target is a function of the distance to and size of the target.
It is particularly important when designing buttons and other clickable on-screen elements. Fitts’s Law is a very appropriate principle to begin with because it’s fundamental to good user experiences and illustrates how neglecting this can lead to confusion or input delays.
Jakob’s Law
Users spend most of their time on other sites, and they prefer your site to work the same way as all the other sites they already know.
The less mental energy users spend on learning an interface, the more they can dedicate towards achieving their objective. While designing the interface we can follow the common design patterns and conventions in strategic areas such as page structure, workflows, navigation, and placement of expected elements such as search.
Hick’s Law
The time it takes to make a decision increases with the number and complexity of choices available.
It is particularly important when designing buttons and other clickable on-screen elements. When users bombarded with choices they will take time to interpret and decide. Choices seem to be good but when response time is critical keep the choices to a minimum. It will speed up the decision making.
Note: Hick’s Law can apply when designing Control display, Dropdown menus, Contact pages, Sign up forms, Button selection, and Navigation menus. Hick’s Law does not apply to complex decision making. If decisions are requiring extensive reading, researching, or extended deliberation. Hick’s Law won’t be able to predict the time to make a decision.
Miller’s Law
The average person can only keep 7 (plus or minus 2) items in their working memory.
The human mind can remember ~7 bits of information when completing a task that requires cognitive effort. This is critical because humans are constantly performing tasks, and trying to juggle various stimuli in the mind when doing so. One of the key concepts behind Miller’s Law is ‘chunking’, which basically means assembling various bits of information into a cohesive gestalt.
Tesler’s Law
Tesler’s Law, also known as The Law of Conservation of Complexity, states that for any system there is a certain amount of complexity which cannot be reduced.
Every UX designer would like to simplify processes and make them faster, but we have to take into account that there are things that cannot be simplified to be more basic. In this case, we transferred it from one place to another. The result of this transfer is that complexity finds its way into the user interface.
